HOSPITAL-BED.

Specification of Letters Patent.

Patented Mar. 11, 1919.

Application led February 1, 191.8.v Serial No. 214,883.

To all whom t 'may concern Be it known that I, DON CARLOS TRAvIs, acitizen of the United States, residing at Kenosha, in the county ofKenosha and State of l/Visconsin, have invented certain new and usefulImprovements in Hospital- Beds, of which the following is aspecification.

My invention relates to improvements in hospital beds, and hasparticular reference to an attachment for supporting a tank ofirrigating fluid,xsuch as is employed for antiseptic purposes accordingto modern hospital practice.

The principal objects of the invention are to provideya support for theirrigating apparatusso organized that it may be eX- tended to ampleheight when in use, while it may be folded down into an inconspicuousposition when it is not desired to use the irrigating device; to providean improved arrangement whereby the irrigating tank support may beemployed as a fracture bar when it is in folded position; to provide animproved arrangement by which the said support may be quickly andconveniently adjusted in folded or extended posit-ion and in general, toprovide an improved construction of the character referred to.

In the drawings which illustrate a preferred embodiment of my invention,Figure 1 is a side elevation of a hospital bed equipped with myinvention, the supporting rod being shown in vertical or extendedposition. f

Fig. 2 is a section taken on the line 2-2 of Fig. 1. Y

Fig. 3 is a section taken on the line 3 3 of Fig. 2.V

Fig. 4 is a side elevation of the rod tip support.

Fig. 5 is an endV elevation of the pivot Vblock and Fig. 6 is a sectiontaken on the line 6-6 of Fig. 1.

The hospital bedstead to which my invention is shown applied, maybe of-any approved design. In the present instance I have shown a metalbedstead of the continuous post type having a head end 10, a foot end11, and a spring 12, the frame of the said spring 12 also constitutingthe side rails of the bedstead. If desired the bedstead may ber equippedwith telescopic extension legs such as 13, and with an adjustableback-rest which, however, is not shown.

or described since general structural features form no part of mypresent invention.

The tank support which comprises a hollow standard 14 in which may betelescopically adjusted an extension rod 13, is supported when inupright position at its lower end by means of a pivot block 15, one sideof which is conformed to lit the tubular post 16 of the foot end 11 asshown best in Fig. 6. The said pivot block 15 may be screwed to the post16 by a pair of flat head screws 17 as shown in 17 in Fig. 5, and isthreaded centrally to receive a thumb screw 18 which extendshorizontally through a circular diametric aperture in the pipe 14. Theouter face of the pivot block 15 is formed with a vertical extendinggroove 19 and an intersecting horizontal groove 20, both of said groovesbeing arranged to lit the surface of the lower pipe 14, so that when thescrew 18 is tightened up the supporting standard 14 is rigidlymaintained in horizontal or vertical position as the case may be.

On the upper end of the extension rod 13,

and by means of a cast joint comprising the clot-hes and is practicallyinvisible in such folded position. Such folding is accomplished by firstloosening the adjusting screw 25 whereupon the rod 13 may be telescopedinto the lower pipe 14 after which the thumb screw 18 is slacked olfsufficiently to permit the rods to swing down into the dotted lineposition shown -in Fig. 2. l Whent-he rods are inthe said horizontal ordotted line position the thumb screw 18 is again tightened so as tosecurely hold the pivotal end of the rod 14. l 0

Special means are provided to rigidly lock the tip end of the supportingrod so as to prevent the parts from shaking, orbecoming damaged throughaccidental displacement. Such locking means comprlses a small bent straplug 26 secured to the bed post by means of a pair of flat head screws 28in order to receive the tip 23 on the end or the extension rod 13. Afterthe tip Q3 has been inserted in the aperture 2S by sliding out theextension rod 13, the same may be locked securely in position bytightening the thumb screw 26.

1t will be observed that When the rods 18 and 14 are locked into thehorizontal dotted line position shoivn in Fig. 2 they may beadvantageously employed to take the place of what is known in hospitalparlance as a fracture bar.

lnasmuch as certain details of the described embodiment may be changedWithout sacrifice of efficiency to suit individual needs andrequirements it should be understood that such detailed description isin no sense a limitation upon my invention, the scope of which should bedetermined by reterence to the appended claims.

l claim 1. ln a receptacle-supporting device for a bed frame, astandard, an alining-block mounted on the frame and provided With avertical groove VJand a horizontal groove, a contact-block provided witha groove, a. bolt traversing the contact-block, the standard and aliningblock and having a threaded connection With the Jframe, said bolt beingadapted to be rotated for pressing the standard in the vertical grooveof the aliningblock for sustaining the standard in an upright positionwhen the receptacle engages the standard, and adapted to be rotated forpressing the standard in the horizontal groove ot said alining-block forsustaining the standard in a horizontal position when the receptacle hasbeen removed therefrom.

2. 1n a receptacle-support for a bed frame, said frame being providedwith a vertical groove and having a horizontal groove intersecting thevertical groove, a tubular, transversely apertured standard having atransverse curvature conforming substantially to the transversecurvature of the grooves, a boit engaging the frame and disposed in thetransverse apertures of the standard and adapted to have a rotatablemovement for pressing the standard within the horizontal groove of thetrame to support the standard in a horizontal position and adapted to berotated for pressing the standard Within the vertical groove ot" theframe to maintain the standard in an upright position Jr`or supporting areceptacle thereon.

3. 1n a receptacle-support for a bed trame, said frame having a partprovided with a bracket and having a part provided With a verticalgroove and a horizontal groove intersecting the vertical groove, atubular, transversely apertured standard having a transverse curvatureconforming substan- Copies of this patent may be obtained for tially tothe transverse curvature ot the grooves, a rod provided With a detentand mounted in the bore of the tubular standard, means to adjust the rodlongitudinally oi said standard, a bolt engaging the frame and disposedin the transverse apertures of the standard and adapted to have arotatable movement While the standard is engaging the bracket formaintaining the standard in a horizontal position, and adapted to have arotatable movement tor pressing the standard Within the vertical grooveof the frame to maintain the standard and its rod in an upright positionfor supporting a receptacle on the detent ot said rod.

4i. 1n a receptacle-support for a bed-frame, said frame being providedWith a vertical groove and having a horizontal groove intersecting thevertical groove, a cylindrical, apertured standard having a transversecurvature conforming substantially to the curvature of the grooves, anapertured contactpiece having a concaved part, a bolt disposed in theapertures of the contact-piece and standard and adapted to have arevoluble movement for pressing the standard `Within the conc-aved partof the contactpiece and horizontal groove of the frame for supportingthe standard in a horizontal position, and adapted to have a revolublemovement for pressing the standard Within the concaved part of thecontact-piece and vertical groove of the trame to maintain the standardin an upright position for supporting a receptacle thereon.
